Red Phalarope

Share on Facebook Share on Twitter Email


Phalaropus fulicaria 8-9″ (20-23 cm). The sea-going habits (swimming buoyantly like a tiny gull) distinguish this as a phalarope; in breeding plumage, the deep reddish underparts and white face and yellow bill designate it as this species. Male duller than female. In fall and winter, both sexes are gray above, white below; in flight suggests a Sanderling, but with a dark patch through the eye.

Similar species: Fall Red-necked Phalarope is darker, with a strongly striped back, blacker crown. Its wing stripe contrasts more; its bill is more needle-like. Thicker bill of fall Red Phalarope may be yellowish at base (usually not). Immature has a black bill.

Voice: Similar to Red-necked Phalarope's whit or prip.

Range: Arctic; circumpolar. Winter range at sea poorly known; from s. U.S. to S. Hemisphere.

Habitat: More strictly pelagic than Northern. In summer, tundra.

The Red Phalarope (called Grey Phalarope in Europe), Phalaropus fulicarius, is a small wader. This phalarope breeds in the Arctic regions of North America and Eurasia. It is migratory, and, unusually for a wader, migrating mainly on oceanic routes and wintering at sea on tropical oceans.

Red Phalarope is about 21 cm (8 inches) in length, with lobed toes and a straight bill, somewhat thicker than that of Red-necked Phalarope. The breeding female is predominantly dark brown and black above, with red underparts and white cheek patches. The bill is yellow, tipped black. The breeding male is a duller version of the female. Young birds are light grey and brown above, with buff underparts and a dark patch through the eye. In winter, the plumage is essentially grey above and white below, but the black eyepatch is always present. The bill is black in winter. Their call is a short beek.

The typical avian sex roles are reversed in the three phalarope species. Females are larger and more brightly coloured than males. The females pursue males, compete for nesting territory, and will aggressively defend their nests and chosen mates. Once the females lay their olive-brown eggs, they begin their southward migration, leaving the males to incubate the eggs and care for the young. Three to six eggs are laid in a ground nest near water. The young mainly feed themselves and are able to fly within 18 days of birth.

When feeding, a Red Phalarope will often swim in a small, rapid circle, forming a small whirlpool. This behaviour is thought to aid feeding by raising food from the bottom of shallow water. The bird will reach into the outskirts of the vortex with its bill, plucking small insects or crustaceans caught up therein. They sometimes fly up to catch insects in flight. On the open ocean, they are found in areas where converging ocean currents produce upwellings and are often found near groups of whales. Outside of the nesting season they often travel in flocks.

This species is often very tame and approachable.

The Red Phalarope is one of the species to which the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA) applies.
